Caution: Touch-screen glass

Applies to: Surface, Mobile devices, and Surface Hub

The touch screen on your device, like most touch screens, is made of glass. The glass can break if your device is dropped or receives a significant impact. To reduce the risk of personal injury, avoid touching the screen if the glass is broken, chipped or cracked and arrange to have the screen replaced.

A cracked or chipped touch screen caused by misuse or abuse of your device is not covered under the Standard Limited Warranty.

CAUTION: Hearing Safety

Frequent or extended exposure to loud noise or sounds when using a headset or headphones can cause temporary or permanent hearing loss. Individual susceptibility to noise-induced hearing loss and potential hearing problems varies. Also, the sound volume produced by a device may vary depending on the nature of the sound, device settings, and the headset or headphones used. As a result, there is no single volume setting that is appropriate for everyone or for every combination of sound, settings, and equipment.

Here are a few common-sense recommendations to minimize your exposure to loud noises or sounds when using a headset or headphones with your device:

Minimize your time listening to loud sound. All of the sound you are exposed to each day adds up. At maximum volume, listening to music or other content on your device with a headset or headphones can permanently damage your hearing in 15 minutes. If you are exposed to other loud sounds also, it takes less time listening at high volumes to cause hearing damage.

The more time you spend exposed to loud sounds, the more likely you are to damage your hearing. The louder the sound, the less time that is required to damage your hearing.

Always turn the volume on your device down before plugging a headset or headphones into your device. Set the volume loud enough to hear clearly in quiet surroundings, and no louder.

Do not increase the volume after you start listening. Your ears can adapt over time so that high volume sounds normal, but the high volume could still damage your hearing.

Do not increase the volume to block outside noise. The combination of outside noise and sound from your headset or headphones can damage your hearing. Sealed or noise-canceling headphones can reduce outside noise so that you don’t have to turn up the volume.

If you can’t understand someone nearby speaking normally, turn down the volume. Sound that drowns out normal speech can damage your hearing. Even with sealed or noise-canceling headphones, you should be able to hear nearby people speak.

To minimize the potential for hearing damage, keep the volume low enough that you can carry on a conversation with people nearby.

Headphones and headsets can attract dangerous objects like staples and paper clips. Always check your headset or headphones before use.

Use of a headset or headphones while driving may be prohibited or restricted in your area; check your local laws and regulations for further information.

Finally, be aware of hearing loss symptoms. It’s a good idea to have your hearing checked regularly by an audiologist. Stop using a headset or headphones with your device and have your hearing checked if:

You experience any hearing loss symptoms

You hear ringing in your ears

Your speech sounds muffled, dull, or flat.

A small percentage of people have a pre-existing vision disorder that may be aggravated when using HoloLens.

Caution: Using mixed reality comfortably

Applies to: HoloLens, Windows mixed reality

Some people may experience discomfort such as nausea, motion sickness, dizziness, disorientation, headache, fatigue, eye strain, or dry eyes when using mixed or virtual reality, particularly as they adjust to using it. If symptoms are severe or persist, consult your doctor.

Motion sickness and related symptoms can occur when there is a mismatch between what you see and what your body perceives. If you are prone to motion sickness, get migraine headaches, have an inner ear disorder, or other health conditions, you may be at increased risk of discomfort.

Viewing 3D or Mixed Reality is not known to harm vision development or cause binocular vision disorders. If you are not able to view the 3-D effect clearly and comfortably, consider consulting an eye doctor, as you may have a pre-existing, undiagnosed binocular vision disorder.

Certain situations can increase your risk of discomfort. For example:

Being a new user – symptoms tend to decrease as you become accustomed to using mixed or virtual reality.

Devices may work best for users whose interpupillary distance (IPD) falls within a certain range. IPD is the distance between the center of the pupils of the two eyes. Users with an IPD outside the optimal range for the device may experience discomfort.

Certain types of content, particularly games or movies that make you feel as if you are moving through space or looking down from above, or interactions that involve tracking moving objects.

Using your device for extended periods without a break.

To reduce the risk of discomfort:

Start slowly and keep your first sessions brief. For most people discomfort should decrease over the first few sessions.

Take breaks periodically and stop and rest if you experience any discomfort. The timing and length of breaks varies by the individual user and how they use their device.

If you experience discomfort, stop using your device and rest until you feel better. Sitting still in a well-lit environment can help speed recovery from disorientation. If you feel disoriented, avoid activities that require balance, coordination, or other capabilities until you recover. Take note of the type of content you were viewing and other aspects of the situation in which the discomfort occurred, so you can adjust or ease into the experience next time. People differ in the time required to adapt. Consider taking more frequent or longer breaks.

Notice: To view 3D content more comfortably

Applies to: HoloLens, Windows mixed reality

Good binocular vision is required to view stereoscopic 3D content. If you have a binocular vision disorder, such as strabismus (eye misalignment, crossed or wandering eye), you may not be able to view 3D content comfortably. A small percentage of people have a pre-existing binocular vision disorder that they might not be aware of until they try viewing 3D content. Consider consulting an eye doctor if you are not able to view 3D content clearly and comfortably.

Warning: Use in safe surroundings

Applies to: Windows mixed reality

Using your device can distract you and keep you from seeing your surroundings. Windows Mixed Reality immersive headsets may fully obstruct your view, and content may appear to be at a distance but still block your view of nearby physical objects.

Always select and use an appropriate AC power supply and/or power cord for your device. Failure to take the following precautions can result in serious personal injury or death from electric shock or fire or in damage to your device.

To select an appropriate power source for your device:

We recommend you use genuine Microsoft power supply units (PSUs) and AC power cords. A genuine Microsoft PSU and/or AC power cord was provided with your device. Genuine Microsoft PSUs or AC power cord can also be purchased from a Microsoft-authorized retailer and at https://store.microsoft.com/devices.

Use only AC power provided by a standard (mains) wall outlet. Do not use non-standard power sources, such as generators or inverters, even if the voltage and frequency appear acceptable.

Confirm that your electrical outlet provides the type of power indicated for your device (in terms of voltage [V] and frequency [Hz]). If you are unsure of the type of power supplied to your home, consult a qualified electrician.

Do not overload your wall outlet, extension cord, power strip, or other electrical receptacle. Confirm that they are rated to handle the total current (in amps [A]) drawn by your device and any other devices using the same circuit.

For devices where the AC prongs may be folded for storage, make sure its prongs are fully extended before plugging the AC power supply for your device into the power (mains) outlet.

For devices equipped with power cords with removable prongs and a universal power supply, make sure the prong assembly is properly configured for the power outlet and fully seated into the power supply before plugging the AC power supply into a power (mains) outlet.
